摘　　要：We successfully synthesized a new cobalt（II） coordination polymer under hydrothermal conditions, [Co（L）0.5（chdc）（H2O）]n （L = 1,4-bis（thiabendazole）butane, H2chdc = 1,4-cyclo- hexanedicarboxylic acid）, which were then characterized by elemental analyses, TG, IR spectro- scopy and single-crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P21/c with a =10.2855（12）, b = 9.3606（11）, c = 20.436（3） A, β = 91.573°, V= 1966.8（4） A3, Z = 4, C20H22CoN3O5S, Mr = 475.40, Dc = 1.605 g/cm3, μ = 1.018 mm-1 and F（000） = 984. The complex possesses a uninodal three-connected hcb Shubnikov hexagonal plane structure with {63} topology. These planes are further linked into a 3D supramolecular network via O-H…O hydrogen bonds involving coordinated water molecules and oxygen atoms of chdc2- ligands. The fluorescence and catalytic activities of the complex for degradation of Congo red in a Fenton-like process were investigated.We successfully synthesized a new cobalt（II） coordination polymer under hydrothermal conditions, [Co（L）0.5（chdc）（H2O）]n （L = 1,4-bis（thiabendazole）butane, H2chdc = 1,4-cyclo- hexanedicarboxylic acid）, which were then characterized by elemental analyses, TG, IR spectro- scopy and single-crystal X-ray diffraction.
